Stationary fuel cell power systems - Part 4.

Performance test methods for small fuel cell power

systems

1 Scope

This Part of GB/T 27748 provides test methods for the electric/thermal and

environmental performance of small stationary fuel cell power systems that

meet the following criteria.

2 Normative references

The following referenced documents are indispensable for the application of

this document. For dated references, only the edition cited applies. For undated

references, the latest edition of the referenced document (including any

amendments) applies.

IEC 61672-1, Electroacoustics - Sound level meters - Part 1.Specifications

IEC 62282-3-200, Fuel cell technologies - Part 3-200.Stationary fuel cell

power systems - Performance test methods

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

condition of a fuel cell power system at ambient temperature with no power

input or output, ready for start-up

4 Symbols

The symbols and their meanings used in this Part are given in Table 1 for

electric/thermal performance and Table 2 for environmental performance, with

the appropriate units.

5 Configuration of small stationary fuel cell power system and test boundary

Figure 2 illustrates the general configuration of small stationary fuel cell power

systems subject to this standard and shows the test boundary and physical

quantities entering and leaving the fuel cell system.

6 Reference conditions

The reference conditions are specified as follows.

7 Heating value base

The heating value of fuel is based on the lower heating value (LHV) in principle.

In cases where LHV is applied for the calculation of energy efficiency, it is not

necessary to add the symbol "LHV", as shown below.

8 Test preparation

An uncertainty analysis shall be performed on the three test items below to

indicate the reliability of the test results and to comply with customer requests.

The following test results shall be analysed to determine the absolute and

relative uncertainty. A test shall be planned so that the reliability of the results

can be evaluated for the following.

9 Test set-up

Figure 3 illustrates an example of the test set-up that is required to conduct

small stationary fuel cell power system testing with gaseous fuel described in

this standard. An electric load and a thermal load are connected to a fuel cell

power system.
